Chris, I suspect its someone who is "painting the tape" as they say. If you want to shake out the weak holders, dump a few shares at as low a price as you can every once in a while. You just might scare someone into blowing out their stock.
As long as these occasional dumps are on low volume I'm not going to worry about them too much. If they start happening with 10-15,000 share trades, then we need to re-think things here...
